Wow, no wonder this coin is so profitable to mine (3x any other major coin).
It's not possible to mine with any older Nvidia cards, and I also failed to get any CPU miner outside "easy-miner" going
About Nvidia cards see here about the .reg file and the -l MxN options:
Strange result.

Compute 1.3 definitely won't work...
It's making windows to think the driver crashed because it's taking long enough without returning a result (windows default is 2 seconds for the GPU) and that's why windows restarts the driver and ccminer won't work and show you impossible hash rate. I made the timeout 40 seconds on my machine (tried with 10 first - it worked for some time, but then it crashed again). This made my laptop second nvidea card to start happily mining with about 22 H/s. Don't do this if you don't have a second video card, because your PC will become completely unusable while mining (if you are cpu mining on the same machine run the cpu miner before running the gpu miner, because otherwise it'll become difficult for you to even start the cpu miner). Here is a link to a .reg file, which will set the timeout to 40 seconds - just double click it and it'll add the setting to the registry (it'll ask you if you are sure). Then you should restart your windows and ccminer should work after the restart. If you find it useful don't forget to tip me

I can play with the numbers a bit without crashing now. The best I've been able to do is 6x120 with higher hashrates. There is definitely a sweet spot you have to find. Hey it's better than what my i5 was doing for sure now.
There is something more to be done about the -l MxN.
About the first number M:
"First of all, your thread block size should always be a multiple of 32, because kernels issue instructions in warps (32 threads). For example, if you have a block size of 50 threads, the GPU will still issue commands to 64 threads and you'd just be wasting them."
About the second number N:
You could find it by gradually increasing it until your card stop working (showing impossible hash rate 3474958.52 H/s) and then restart is needed for maximum performance (but not for testing), because without restart my hash rate is felling 2x compared to the same options before the crash.
The "magical numbers" for 650M seems to be -l 128x5

Thank you!
About the CPU miner I was testing all the CPU miners available (Wolf, yam, LucasJones, SimpleMiner) on multiple windows and linux 64x configurations (different processors, with AES-NI or without AES-NI). What are the problems you are facing?
Edit: It seems the yam miner is currently the faster CPU miner, but there is a dev fee (min 1%, max 50% depending on what you want to give for yam dev).
Command line just says 3 miner therads started, sets diff, and keeps saying stratum detecetd new block and resets diff.
No hash tho.
This is normal - try a pool/port with lower starting diff. Sometimes Wolf miner without AES-NI don't send the shares, so I was using LucasJones when AES-NI was not present (google your processor if it have AES-NI). Now I'm using yam in both cases, but I'm not sure it's faster on non-aes-ni.
